Report in Two Languages
You see simple recommendations in plain language. Your developer gets technical details with HAR files and waterfall. One test — two formats.
💼 Show the clear report to clients, technical version to developers.
What is a HAR File and Why Does It Matter?
A HAR (HTTP Archive) file is like a complete recording of everything that happens when someone visits your website. It captures every image, script, font, and API call — along with exactly how long each one takes to load.
